Description

The Excelltel MS208 is a compact and affordable analog PABX system designed for small offices, clinics, or home use. It supports two incoming telephone lines and eight internal extensions, making it ideal for environments that require simple internal communication and shared external line access.

This unit offers built-in automated call handling via a DISA system and operator extension mode, enabling callers to reach specific internal phones directly. A configurable outgoing greeting message provides professional call routing. All major call control features are supported, including internal call transfer, call pickup, call restriction, and conference calling.

The MS208 supports caller ID, external music on hold, and allows connection of doorphone intercom units with lock control, making it suitable for small facilities requiring secure access and visitor handling. It includes failover behavior to route CO lines directly to key extensions in case of a power outage, and settings are preserved through internal memory backup.

With its small size, easy installation, and low cost, the Excelltel MS208 is a popular choice for non-IP based office setups that rely on analog telephony infrastructure.
